IMPROVEMENT IN EMBROIDERY ATTAOHMENTS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 148,761, dated March17, 1874; application filed February 7, 1874.

To all Ywhom it may concern:

Be it known that I, REUBEN M. Rosn, of Williamsburg, Brooklyn, in thecounty of Kings and State of New York, have invented certainImprovements in Embroidery Attachments to Sewing-Machines, of which thefollowing is a specification:

This invention relates to embroidery attachments to sewing-machines thatoperate to lay an embroidery-thread upon the upper surface of thefabric, and which is secured by an independent sewing-thread, twoneedles and a shuttle, or their equivalents, being used. Furthermore,the embroidery-stitch made by my invention is a well-known one, the sameconsisting of a succession of coils which the sewing-thread is made tointerlace, to accomplish which my invention admits of ordinary-shapedneedles being used. To these ends my invention generally consists in apressure-foot attachment which may be applied to any ordinarysewing-machine in place of the usual foot, and has combined with itahorizontally-reciprocating eye-pointed needle and mechanism foroperating the saine by the sewing-needle bar, so that theembroidery-thread, which is carried by the horizontal needle, is firstworked by the latter in front of the sewing-needle, then moved laterallyby a positive motion applied to the horizontal needle, that is thusthrown back of the sewing-needle during the ascent of the latter andacross its path, and subsequently returned laterally to its normalposition', while the sewing-needle in its descent enters the loop of theembroidery-thread, which, by the straight reciprocating action of thehorizontal needle in line of the feed and its lateral action combined,coils the embroidery-thread, as it were, around the sewingneedle.

In the accompanying drawing, Figure l represents a front elevation of myembroidery attachment in relation with the sewingneedle when the latteris down, Fig. 2, a like view of similar devicesbut showing thesewing-needle as in the act of ascending, shortly before theembroidery-needle is thrown laterally back of it 5 Fig. 3, a plan withthe ,parts in the position represented in Fig. 1; Fig. 4, a plan afterthe embroidery-needle has been thrown back of the sewing-needle, andFig.

A is the presser foot or shoe, provided on the upper surface of itsbearing portion with a horizontal slide, B, moving in direction of theline of feed, and which may be guided in its reciprocating movement byslots b and pins or projections c. G is the bed or table of thesewing-machine, and D the material to be embroidered. The horizontalslide B has attached to it, in advance of'its forward end, a horizontaleye-pointed needle, E, which carries the embroidery-thread d, and whichis so arranged, relatively to the sewing-needle F, that, in the forwardmotion of the slide, it causes the horizontal needle E, with itsembroidery-thread d, to be projected in front of the sewing-needle Fshortly before the latter completes its ascent, as represented in Fig.2. The sewing-needle F then completes its ascent, and, in doing this,the needle E, bearing against or lying immediately in front of theneedle F, is moved laterally by a positive motion to the back of theneedle F as the latter, in its ascent, clears the horizontal needle E.This leaves a loop, e, of the embroidery-thread, as shown in Fig. 4,through which loop the needle F, in its succeeding descent with itssewing thread f, passes, and the horizontal needle E moves laterally toits normal position in a line which is in advance of the needle, andsubsequently moves backward in direction of the feed,while thesewing-needle F completes its descent and forms slack, through which ashuttle-thread is passed to lock the sewing-stitch. The horizontalneedle E then moves forward again, with its embroidery-thread d, infront of the sewing-needle F, for a repetition of the action, asdescribed. In this way, or by these means, the embroidery-thread iscoiled, as it were, around the sewing needle. The horizontalreciprocating action of the needle E in line of the feed is elected by abell-cranked lever, G, the one arm of which is connected with the slideB, and the other, preferably by a cord or .its equivalent, with theneedle-bar H, or screw that holds the sewing-needle, so that thesewing-needle .may have a dwell motion for the passage of the shuttlebefore vlifting on the lever G to project the horizontal needle in frontof the sewing-needle. The reverse mover ment of the lever G, which drawsthe horizontal needle E back as the sewing-needle E makes its descent, Iprefer to effect by means of a spring, 7L,- birta positive motion may beused instead, if desired. The lateral throw or movement of 'the needleEback of the sewingneedle, as the latter completes its ascent, iseffected in a positive manner. Thus the needle E is attached to aspring, I, which is carried by the slide at t', and is crooked at k, sothat as the slide makes its forward movement it or the crook k comes incontact with a stop, I, which moves the needle E laterally back of thesewiiignecdle, and so that when the latter commences its descent thespring I throws the needle E laterally in a reverse direction to aposition in line with the front of the sewingneedle, as required.Instead of the spring I, however, the needle E may be attached to apivoted bar or lever which is made to receive a positive lateral motionin both directions as the slide B is reciprocated; but it is preferredto use the spring I, as such provides for irregularities of theneedle-thread.

I claimy l. The combination, with the presser-foot, of the slide B,arranged to reciprocate in direction of the line of feed, and carryingtheA 3. The combination of the lever Gr with the' slide B and needle E,having a lateral as well as a reciprocating motion relatively to thefeed, as described.
